scope:

This Specification applies to critical pump sites. These are pump sites where structural or serviceability failure would result in restrictions to the operational railway (e.g. by track or station closure) within 24 hours. Refer to the current version of London Underground (LU) Category 1 Standard 1-056 Civil Engineering - Pumping Systems for the detailed methodology concerning determination of pump site criticality. The LU Asset Management System (AMS) is called ELLIPSE; all critical pump sites are labelled as such in ELLIPSE.

Purpose

The purpose of this Specification is to provide designers and tenderers / contractors with the minimum technical standards and physical requirements that pump control equipment (at critical pump sites) shall be designed and constructed to meet.
